If minimum frequency (par 1 ..... 1) >0, If minimum frequency (par 1 ..... 1) = 0,
hysteresis is ± 2% at reversing point. there is no hysteresis at reversing point.

- switch in DIB5 closed = frequency reference increases
- switch in DIB6 closed = frequency reference decreases

This parameter determines the maximum motor current from the freqeuency

of the motor.

Linear: The voltage of the motor changes linearly with the frequency in the
0 0
0 0 0 constant flux area from 0 Hz to the field weakening point (par. 6

where the nominal voltage is also supplied to the motor. See figure
5-2. Linear U/f ratio should be used in constant torque applications.
